SHUTTLE BOX FOR LOOMS.

Application filed November 12, 1924. Serial No. 749,529.

This invention relates to improvements in shuttle boxes for looms and anobject of the invention is the provision of surfaces of revolutionrotatable in one direction to reduce friction but held against rotationin the other direction to increase friction against the shuttle.

In very broad looms where the shuttle is surfaces of revolution shouldrotate as the.

shuttle enters the box.

It is to be understood that as shown in the drawings herewith the rollswill prevent rebounding of the shuttle, this feature making its use onrelatively narrow looms desirable as well as on the broader looms.

Another object of my invention is to provide a plurality of surfaces ofrevolution rotatable in one direction only associated with a rollingsurface mounted on the protection finger.

With these and other objects in view which will appear as thedescription proceeds, my invention resides in the combination andarrangement of parts hereinafter described and set forth in the claims.

in the drawings, Fig. 1 is a top plan view 'of a shuttle box having myinvention applied thereto.

Fig. 2 is a front elevation of a lay showing the shuttle box, protectorfinger and the rolls, one of which is indicated in section, and

Fig. 3 is an enlarged detailed fragmentary front elevation of the lowerend of one of the rolls showing the means for preventing retrogrademovement.

Referring to the drawings it will be seen i that 1 have provided a layprovided with a box plate 11 and lay end 12 from which extends boss 13.A box back 14 of any desired construction may be employed and isprovided with aflat friction surface 15 forming the rear wall of thebox.

My invention relates more particularly to the formation of the frontpart of the box and it will be seen that I have provided a plurality ofstuds each having a head 21 and provided with loose collars 22 whichextend between a shoulder 23 and the box plate. The studs have threadedshanks 24 extending through slots 25 in the box plate to receive nuts 26by means of which the studs are held in fixed relation with respect tothe box. Mounted loosely between the head 21 and the washer 22 of eachof the studs 20 is a roll 27 having a surface of revolution indicated at28 which may be made of any desired material, such as leather or fiber.The lower end of each roll is formed With ratchet teeth 29 as shown inFig. 8, where it will be seen that a spring detent 30 is secured to thebox plate by means of screw 31. There is a detent for each roll on thebox plate. The teeth and detents as shown herein permit rotation of therollers 27 in a clockwise direction as viewed in Fig. 1 but preventrotation in a counter-cloclnvise direction. It is to be understood thatI may furnish as many of the rolls as are necessary and that the latterare positioned forengagement with the front wall of the shuttle S, beingopposite the surface 15 and cooperating therewith to exert lateralpressure against the shuttle in all angular positions of the roll.

Fixed to protector rod 32 which is received by boss 31 is a protectorfinger 33 the upper end of which is provided with a stud 34c and collar35 similar to stud 20 and collar 22, respectively. The stud 34 supportsa roller 36 which is freely rotatable in both directions'and cooperateswith the fixed rolls to exert pressure on the shuttle.

From the foregoing it will be seen that I have provided a shuttle boxwith a plurality of surfaces of revolution rotatable in one directiononly and located so that said surtions may be made therein by thoseskilled in the art Without departing from the spirit and scope of theinvention, and I do not wish to be limited to the details hereindisclosed, but What I claim is:

1. In aloom, a shuttle box, a frictional surface forming part of the boxto engage one part of the shuttle and fixed relatively to the box, andsurfaces of revolution forming another part of the box and spaced fromthe fixed surfaces to engage other parts of the shuttle and be rotatedthereby in one direction only as the shuttle moves in the box.

2. In a loom shuttle box, a plurality of shuttle-engaging rotary membersto resist movement of a shuttleand forming one side of the box androtatable in one direc ion only.

In a loom, a shuttle box, and'means associated with the box to haverolling contact with the shuttle as the latter moves in one directionand having sliding trio tional contactwith the shuttle as the lattermoves in the opposite direction.

In a ioom, a shuttle box, a surface of revolution associated with thebox to engage the shuttle as the latter enters the box, and means topermit said surface of revolution to rotate in one direction only.

therewith, one of said surfaces 01 In a loom, a shuttle box, rotarymembers fo iig one of the shuttle engaging sides of the box andpositioned to engage the shuttle and have frictional contact therewithwhen the shuttle is in the box, and means including a pawl and ratchetto prevent movement of the rotary members in one direction.

6. In a loom, a lay, a shuttle box, a fric tional shuttie engagingsurface fixed rela- M tively to the shuttle box, means presenting surfao"? revolution to engage the shuttle and spaced. form the first namedsurface, the surfaces of revolution being subs tially the same distancefrom the fixed fric- 131 tion surface in all angular positions of sai'csurfaces of revolution, and means to permit rotation of said surfaces ofrevoiution in one direction only.

a lay, a shuttle box t 1. in a loom, a protector finger mounted on thel. a plurah of spaced surfaces of tion forming one of the shuttie ensides of the box to resist movement 0: shuttle in the box and have rolhtion being mounted on the protector I In testimony whereof I havehereunto aflixed my signature.
